Ibis Oso HD Frameset 2026

Downhill Both Ways.

The Ibis Oso HD Frameset is the gravity-focused foundation of the Oso platform, ready to build up for shuttle laps and big mountain lines. With 165mm of rear travel and geometry tuned for fast, technical descents, it's the most capable personality in the Oso lineup. Bolt-on dropouts let you configure chainstay length and wheel size to match your terrain, with all dropout options available aftermarket. The frame ships with a Fox Factory Float X2 rear shock and is optimized for a 180mm fork. With a Bosch Performance Line CX Gen 5 motor that boasts a low and centered 600Wh battery position and compatibility with a clean PowerMore integration for up to 850Wh total when the day demands it. 

Features

  • Fox Factory Float X2 rear shock included 230x65mm, optimized for 165mm of rear travel
  • Optimized for a 180mm fork (597.5mm axle to crown) with gravity-focused geometry built for fast, technical terrain
